1 Features Low profile 4.mm Low cost Wide input range (5V - 36V) Short circuit protection Casellated connections Description The is a switching regulator with a wide input voltage range, high effi ciency and a low profi le, pin-less SMD package. Two low-ripple put voltages are available as standard: 3.3V or 5V with ma continuous put current rating over the full operating temperature range of - C to +75 C with derating. An enable connection allows power sequencing or very low standby consumption (3.5µA) for battery powered applications. These modules can be SMD refl ow soldered. The connection pads have corner half-vias to enable optical inspection of the joints after soldering.
